APPLICATION TESTS for thePHASE V ARTHUR
RESPIROMETERDevelopment of the following tests by Arthur Technology (now Respirometry Plus) began over 40 years ago when the Arthur Respirometer was introduced. The tests have been used by operators, technicians and consultants worldwide. Customersreceive detailed written instructions for performing these tests, or they may choose to learn through our Distance Trainingprogram - one-on-one training sessions conducted by phoneand fax.

. Troubleshooting Tests - These tests should be run while the plantis functioning well. With graphs of "good operation" in hand, you will bewell prepared to pinpoint and solve problems quickly when they occur.

Preparing the TestIn one chamber suspect sample isadded to endogenous sludge fromthe wastewater plant. Endogenoussludge alone will be added to theother chamber as a comparison.

COMPOST & BIOSOLIDS TESTING

Compost Process Control Testing

The Arthur Respirometer is capable of measuring respirationof raw samples by providing a continuous record of changes in oxygen use. In this application the solid compost is placed on a tier of perforated stages within the sample chamberand air circulates freely through the compost..

Stability Testing of the Final Product - A Stress Test

In this test, the compost sample is tested in anacqueous solution. This produces an environmentin which there is intimate contact of food, micro-organisms and oxygen. Even small amounts offood are available for metabolizm by themicroorganisms. This test ensures that the compostis stable.

Soil Biodegradability Testing - using either the Automated or the Simplified Respirometer.

Landfills have become a common method of disposing of municipal solidwastes in many communities.If the waste products are organic, it is likely that metabolic activity (probably anaerobic) will take place. The probabilityof it taking place can be determined by either performing solid tests oracqueous tests in the respirometer. Either method will determine whetheror not toxins are present in the landfill.
